    Being a Norh American, I was always under the impression that the aboriginal people arrived here via the Bering Sea land bridge connecting with Asia that formed during last ice age. Surprised to learn that the land bridge (Beringia) acted as home for their actual ancestors for thousands of years, prior to migrating into America. I find the science and the interpretation of evidence pretty remarkable here.

    What I don't understand is why would they have settled there instead of continuing on? I thought we as humans have an innate passion to explore. Was Beringia ice covered during that time and if not why not?


    All that belongs to human understanding, in this deep ignorance and obscurity, is to be skeptical, or at least cautious; and not to admit of any hypothesis, whatsoever; much less, of any which is supported by no appearance of probability...Hume

    We are also inherently lazy, cautious, conservative and indolent. Why would we move on to a complete unknown if we had found somewhere that was adequate or better? A journey of an entire tribe, with the full gamut from babes to tribal 'ancients', for a thousand miles of more, would have likely exceeded the logistical capabilities of the tribe by a considerable margin.

    The exploration passion you speak of, coupled with pressures from other tribes, natural fluctuations in resources, etc. would have led to a move to the next valley, or across the next watershed. Repeat that every generation or so and moves of a few miles build up to the populating of a continent.

    Things must have been good. The Beringia land bridge was occupied for 15000 years according to the study, by one single group of hominids. Other than that it was awfully hard to find(google) another group similar to that in our history unless you want to include our African ancestors who occupied that continent, but even they moved around. Can't guarantee the accuracy but from Wiki:

    Historical migration of human populations begins with the movement of Homo erectus out of Africa across Eurasia about 1.75 million years ago. Homo sapiens appear to have occupied all of Africa about 150,000 years ago, moved out of Africa 70,000 years ago, and had spread across Australia, Asia and Europe by 40,000 years BCE. Migration to the Americas took place 20,000 to 15,000 years ago. Nonetheless, by 2,000 years ago, most of the Pacific Islands were colonized.
    Perhaps not an entire tribe would pull up stakes but a few adventurous, curious or banished members might. My mistake to say that all of us have the innate desire to explore. I really meant that there would be a likelihood of some individuals with that passion who would act on it. History/evidence tells us that humans moved around.

    Primitive humans can inadvertently migrate huge distances, IF environmental conditions coax them along and their lifestyle is marine. I mean practically living out of small watercraft like the Aleut did. Toward the end of the otter pelt trade (begun by Russians), Aleuts in their primitive kayaks were documented off the coast of Los Angeles. Those oldtimers had gradually meandered south as they depleted the otters.

    People doing subsistence in the high arctic were affected by resource scarcity to a degree that's hard to appreciate. Small family groups had to migrate regularly and keep themselves spread thin across a region of minimal carrying capacity. If ice age conditions were similar then just doubling a family size meant everyone starves because they literally eat their local food to extinction. That, or a few members must seek subsistence elsewhere.
